Abstract

The invention discloses an air heat exchanger of a reactor and the reactor. The air heat exchanger is used for heat exchange and cooling of a coolant of the reactor. The air heat exchanger comprises a shell, a heat exchange piece and an air blower. The shell is provided with a first air inlet and a second air inlet. The heat exchange piece is used for allowing a coolant to flow. The air blower comprises an air blower outlet communicating with the first air inlet so that the air blower can press and feed air to the heat exchange piece. When the reactor is in a normal working condition, the first air inlet is opened and the second air inlet is closed, and the air blower operates to supply air to the heat exchange piece through the first air inlet; when the reactor is in the accident condition, the first air inlet and the second air inlet are opened, and the air blower is powered off to provide air of the external environment for the heat exchange piece through the first air inlet and the second air inlet. The air heat exchanger provided by the embodiment of the invention can stably operate in a normal working condition or an accident working condition of a reactor, heat exchange is carried out on a coolant, and the reliability and the safety of the reactor are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of reactors, in particular to an air heat exchanger of a reactor and a reactor. Background technique [0002] The sodium-air heat exchanger is one of the key devices in the heat transfer system of the sodium-cooled fast reactor, which is used to transfer heat from the reactor's secondary loop cooling system to the atmosphere. [0003] However, the sodium-air heat exchanger in the related art cannot take into account the stable operation under normal working conditions and the waste heat discharge under accident working conditions. Contents of the invention [0004] An embodiment of the present invention provides an air heat exchanger for a reactor and a reactor. [0005] An air heat exchanger for a reactor according to an embodiment of the present invention is used for exchanging heat and lowering the temperature of a coolant of the reactor. The air heat exchanger of the reactor inc...
